Canada high resolution dem
WebSpatial resolution, particularly for raster data collected through remote sensing or LiDAR, is typically determined by the sensor capabilities used to collect the data. In short, a higher resolution dataset, for example a DEM with a 1 meter spatial resolution, will require more storage space compared to a DEM with a spatial resolution of 20 meters. WebThe Reference Elevation Model of Antarctica (REMA) is a high resolution, time-stamped Digital Surface Model (DSM) of Antarctica at 2-meter and 8-meter spatial resolutions. Mosaicked DEM files are compiled from multiple strips that have been co-registered, blended, and feathered to reduce edge-matching artifacts. dem geophysical pgc rema umn
